Chordospartium stevensonii is a leafless, small tree of weeping habit, which grows to 12–24 ft (3.6–7.3 m) high. The pendulous branches are about 0.07 in (1.75 mm) in diameter. The pale, rose-lilac flowers are in racemes, carried either singly or in groups of 2 to 5.
Chordospartium stevensonii grows in alluvial soil along the tributaries of the Awatere, Clarence and Wairua Rivers, Marlborough, South Island, New Zealand. It is hardy in the UK and grows best in a sunny spot, but it is probably not long-lived here.
